Direction: In the following question, two statements are given. You have to find out whether the data in the statements is sufficient to answer the question. On which day does Meena celebrate her birthday? I. Meena's brother's birthday is on 20th December, and her mother's birthday is 8 days after her brother's birthday. II. Meena celebrates her birthday 5 days after her father celebrates his birthday. Her father celebrates his birthday on 22nd December, which is 6 days before her mother's birthday.

1. Only I is sufficient
2. Only II is sufficient
3. Both are required
4. Either I or II is sufficient

Correct answer: Only II is sufficient

Solution

Statement I only tells us the brother's and mother's birthdays, but not Meena's. Statement II says the father’s birthday is 22nd December and Meena’s birthday is 5 days after that, so Meena’s birthday can be determined uniquely. Therefore, only II is sufficient.
